11．At thirteen，I was diagnosed with a kind of attention disorder．It made school difficult for me．When everyone else in the class was focusing on tasks，I could not．
In my first literature class，Mrs．Smith asked us to read a story and then write on it，all within 45 minutes．I raised my hand right away and said，"Mrs．Smith，you see，the doctor said I have attention problems．I might not be able to do it．"
She glanced down at me through her glasses，"You are no different from your classmates，young man．"
I tried，but I didn't finish the reading when the bell rang．I had to take it home．
In the quietness of my bedroom， the story suddenly all became clear to me．It was about a blind person，Louis Braille．He lived in a time when the blind couldn't get much education．But Louis didn't give up．Instead，he invented a reading system of raised dots（点），which opened up a whole new world of knowledge to the blind．
Wasn't I the"blind"in my class，being made to learn like the"sighted"students？My thoughts spilled out and my pen started to dance．I completed the task within 40minutes．Indeed，I was no different from others； I just needed a quieter place．If Louis could find his way out of his problems，why should I ever give up？
I didn't expect anything when I handed in my paper to Mrs．Smith，so it was quite a surprise when it came back to me the next day-with an"A"on it．At the bottom of the paper were these words："See what you can do when you keep trying？"

解答 21．B 细节理解题．根据第一段的I was diagnosed with a kind of attentiondisorder…When everyone else in the class was focusing on tasks，I couldnot．可知作者患有一种注意力障碍的病症，当班上的每个人都专注于任务时，他不能．所以作者在专注于任务时有困难，故选B项．
22．A 句意理解题．根据In the quietness of my bedroom，thestory suddenly all became clear to me．可知字面意思为：在我卧室的静谧中，故事突然变得清晰起来以及下文讲述这个故事的大意：Louise Braile是个盲人，创造了盲文．所以画线的句意是作者明白了故事的意思．故选A项．
23．C 主旨大意题．本文主要讲述作者患有注意力障碍的病症，不能集中精力于所做的事情，不愿努力而且想放弃．在Louise Braile故事的激励下，终于克服困难很好地完成作业并得到老师高度认可的故事．所以文章的主要内容是：一个人可以通过努力找到困难的出路．故选C项．
点评 本文是科教类阅读，主要考查细节理解题和推理判断题．在做细节理解题时，首先根据题目要求迅速在文章里找出相应的段落、句子或短语．认真比较选项和文中细节的区别，在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
